U.S.-Sweden Cooperative Research: Numerical Studies of Vortex Matter in High Tc Superconductors and Superconducting Films

该奖项支持PI和与瑞典于默奥大学理论物理系的Peter Minnhagen和Peter Olsson合作的研究生。该项目将集中于涡线和点涡模型的数值模拟，以研究与高Tc超导体和超导薄膜行为相关的问题。结合PI在三维波动涡线平衡行为方面的经验和瑞典小组在动力学模拟方面的经验，将有可能探索与高Tc超导体中涡线动力学相关的几个高度热门和相关问题。这些包括约瑟夫森等离子体共振和涡旋线液体中的通量流动阻力。合作的一个主要组成部分将是使用于默奥现有的专门超级计算机设施，这将大大扩大国内研究活动的范围。

The project will focus on the numerical simulation of models of vortex lines and point vortices, in order to investigate problems relevant to the behavior of high- Tc superconductors and superconducting films. Combining the PI's experience in the equilibrium behavior of fluctuating vortex lines in three dimensions with the Swedish group's experience in dynamical simulations will make it possible to explore several highly topical and relevant problems related to the dynamics of vortex lines in high- Tc superconductors. These include the Josephson plasma resonance and the flux-flow resistance in the vortex line liquid. A major component of the collaboration will be the use of specialized supercomputer facilities available in Umea, which will greatly broaden the scope of the domestic research activities.
